Has anyone actually used this to charge their cell phone? In my experience that supposed feature never works on these things. Any success anyone?

I used this feature during Hurricane Irma, but the "charging" was minimal. The radio had a hard time holding power to broadcast while also charging the phone. My suggestion to anyone who is looking for a phone charging option in case of loss of power is to buy a backup power cell with a USB port for your phone to plug into. Much more reliable than trying to use the crank radio. All other features on this radio work well, though.

After 6 hours of charging mine the red light won't go out. How do I know it's charged?

Please kindly be noted that the charging light staying in red is a symbol to show that the radio is fully charged, which means the charging light will not turn green. However, if the charging light flashes red, then it means that the item is still in charging. Hope this will help.
